Abstract:
Objective:To investigate the effects of trazodone on the growth, motility and ferroptosis of endometrial carcinoma cells, and to study its effect on phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/ mechanistic target of rapamycin (mTOR) signaling pathway.Methods:Human endometrial carcinoma HEC-1A cells were divided into a control group and an experimental group. HEC-1A cells in the control group and in the experimental group were treated with 0 and 2 μmol/L trazodone dimethyl sulfoxide solution, respectively, for 24 h. Cell growth was evaluated by cell counting kit-8 and colony formation assay, cell motility was evaluated by scratch assay, Transwell assay and Western blotting, ferroptosis was evaluated by Western blotting and iron detection kit, and the effect of trazodone on PI3K/Akt/mTOR signaling pathway was evaluated by Western blotting. Analysis and comparisons were made using one-way analysis of variance and Tukey′s multiple comparisons.Results:The cell survival rate [(32.2±3.2%)] and the number of cell clones (18.0±4.0) in the experimental group were lower than those in the control group [(99.2±4.3)% and 35.0±5.0], and the differences were statistically significant (both P<0.01). The relative scratch width of the experimental group (0.57±0.07) was higher than that of the control group (0.24±0.05), and the difference was statistically significant ( P<0.01). The number of invasive cells in the experimental group (7.0±1.0) was lower than that in the control group (15.0±2.0), the difference was statistically significant ( P<0.01). The relative expression levels of matrix metalloproteinase-9 (0.50±0.05) and matrix metalloproteinase-2 in the experimental group (0.75±0.08) were lower than those in the control group (0.82±0.07 and 1.25±0.15), and the differences were statistically significant (both P<0.01). The iron level [(190.5±18.5)%] and the relative expression level of acyl-CoA synthetase long-chain family member 4 (0.63±0.06) in the experimental group were higher than those in the control group [(99.2±8.9)% and 0.38±0.05)], and the differences were statistically significant (both P<0.05). The relative expression level of glutathione peroxidase 4 in the experimental group (0.22±0.05) was lower than that in the control group (1.22±0.13) ( P<0.01). The levels of phosphorylated PI3K/PI3K, phosphorylated Akt/Akt and phosphorylated mTOR/mTOR in the experimental group (0.62±0.08, 0.35±0.05, and 1.46±0.18) were lower than those in the control group (1.47±0.16, 1.32±0.11, and 2.34±0.11), and the differences were statistically significant (all P<0.01). Conclusions:Trazodone may have an anti-tumor effect on endometrial carcinoma cells by inhibiting the growth and motility of tumor cells, promoting ferroptosis, and inhibiting the PI3K/Akt/mTOR signaling pathway.
